Creating nested hash from nested active record results

Creating nested hash from nested active record results

Creating nested hash from nested active record results

(OP)
Hello,
I'm trying to find a very abstract and "one size fits all" for converting nested active record results to nested hashes. It's easy, to do one level deep as such:

CODE

results_to_hash = Hash[ found_categories.map{ |c| [c.id, c.title]}] 

But, when I try to add another collection to the mix, it completely borks and the results_to_hash only returns an empty hash IE:

CODE

results_to_hash = Hash[ found_categories.map{ |c| [c.id, c.title, c.categories]}] 

Ultimately, I'd like it to be smart enough to detect if a model object contains a collection (IE: object.class.reflect_on_all_associations), and automatically convert those to hashes.


Any ideas?

Thanks,
Eric
